I'm using kernel 2.6.14.2 with md (RAID1 static) as bootable. While md synching (initial creation or after marked one as failed, removed and re-added) there are some locking problems with the complete system/kernel. Sometimes the system hangs (looks like a file/disk-access-lock) while other tty's still work (until they access also to the disk). This "hang" is some seconds (most from 10s up to 1 minute, seldom more) and surprisedly the system continues working. If md is in correct state (all partitions synced) this issue doesn't seem to appear. Configuration 4 Partitions (/boot 1GB, / 32GB, swap 16GB, /home 250GB) on MaxLine III SATA 300GB Disks. Each of them (including swap) is a RAID 1 device in the listed order. This system has a Opteron 270 with nVidia Professional Chipset. There are NO log entries found anywhere and no console warning/error. These are 4 systems with she same behaviour. Did anybody ever reported such an issue or has an idea?
